    Modeling suggestions for my problem, please

    Great points from everyone! It's really helping me flush out my project. What I'm modeling are flexible needles. When inserted into tissue, the tissue places a transverse force on the face of the bevel, causing the needle to curve downward. I am interested in modeling this downward curvature of...

    Modeling suggestions for my problem, please

    That's the goal of the project, to model different needle geometries as well as materials (including plastics) to view the effects of strain, strain rate and stress on tissue. I am trying to model in Standard, yes. The inputs to the simulation are a 0.1 mm "push" on the back of the needle into...

    Modeling suggestions for my problem, please

    Thanks everyone for your helpful insights. So, since it seems that meshing the fillets is tricky, I decided to start with an easier problem. I'm just trying to insert a standard bevel-tipped needle into tissue. The dimensions of the bevel are 0.711mm diameter cylinder, 4.03mm long on the bottom...

    Modeling suggestions for my problem, please

    Hello. I am rather new to ABAQUS FEM and would be very grateful for some input on my model and study design. My overall goal is to model how the tip of a needle interacts in human tissue. Specifically, I am interested in looking at the stress, strain and strain rate for small needle...
